Title: An improved machine for the mechanical treatment of metal sheets to be subsequently drawn, pressed or otherwise worked
IPC: B21D1/02
Filed: 1926-05-29
Abstract: 252,738. Budd Manufacturing Co., E. G., (Assignees of Kelley, G. L., and Eksergian, C. L.). May 29, 1925, [Convention date]. Valves controlled by pilot or relay valves.-In apparatus for cold working metal sheets, the working roll &c. is moved automatically into and out of working relation to the sheet by means controlled by the passage of the sheet through the machine. When a sheet is fed between the rolls 13 up to the rolls 11, the circuit of a battery 24 is completed, as shown in Fig. 6, tu a combined electromagnetic relay 21 and pneumatic relay 22, bringing into operation a pneumatic cylinder 15, the piston rod 16 of which swings over a crank 17 on the shaft 68, raises the roll 12, and establishes a working bend 20 in the sheet. The circuit is broken when the rear end of the sheet passes the rolls 13. The making of the current in the electromagnet 50, Fig. 3, lifts the core 49 and rod 48, and opens the poppet valve 51 so that compressed air passes along the passages 52, 46, 43, 42, 41 under the piston 36 of the pneumatic relay 22, the movement of the piston lifting a valve 29 establishing communication between the air supply chamber 28 and a chamber 31 which serves the pneumatic cylinder 15 by a conduit 23. Breaking of the current on the electromagnet 50 opens the underside of the relay cylinder 35 to the air through the passage 54, and the consequent descent of the relay piston 36 closes the valve 29, opens the valve 32 below it, and opens the main cylinder 15 to the air through the discharge chamber 33 and port 34. Insulating caps are fitted between the guide rolls 13 and the pinson which they are journaled.

Filed: 1960-04-21
Abstract: 910,848. Sewing-machines. MOHASCO INDUSTRIES Inc. April 21, 1960 [Aug. 27, 1959], No. 14015/60. Class 112. Pile fabric comprising successive transverse rows of cut and uncut loops arranged according to a pattern is made by feeding increments of the pile yarns towards the loop-inserting position in accordance with the pattern, feeding the work lengthwise after the insertion of a row of loops, and then cutting those loops which exceed a selected length. To produce the fabric, the machine described in Specification 825,581 is modified to cut all the loops of maximum length. Yarns P<1> are fed to needles 24 by interleaved elements 34, 39 mounted on endless chains 33 38, the height of the elements being varied in accordance with the desired pattern. Loopers 27 co-operate with the needles to form loops L<1> of maximum length. A bar 44, attached to the needle bar 19, deflects the yarns upwardly between the yarn-feed elements and the needles when the latter rise, whereby yarn is withdrawn from those needles to which an increment of yarn less than that required for the formation of a loop of maximum length has previously been fed. When the work is next fed, the loops of maximum length encircle respective fixed cutting-blades 41 and are cut thereon, when the yarn is next stationary, by movable blades 42. The loops L of less than maximum length pass uncut over the blades 41. Thin fixed plates 43 are arranged with their free edges lying close to the need les and above the loopers so as to engage the loops when these are released by the loopers, to prevent, the loops from twisting out of a plane transverse to the direction of work feed. Reference has been directed by the Comptroller to Specifications 825,581, 825,582 and 825,583.

Abstract: 1344841 Fuel injection pump AUTOMOBILES PEUGEOT 11 May 1971 [8 June 1970] 14308/71 Heading F1A In a "distributor" or "in-line" fuel injection pump wherein the quantity delivered to an injector outlet 6 is modified by allowing part of the fuel delivered from the pumping chamber 9 to enter a fixed or variable volume deduction chamber 43, a piston member 35 prevents deduction occurring above a predetermined speed. Fuel deducted enters the chamber 43 via passages 7, 24, a non-return valve 30 and a throttle 40 in the piston member 35. Because of the pressure drop across the throttle 40, the piston member 35 is displaced to the right against the action of a spring 37. This closes a return passage 38 for the deducted fuel until the spring 37 returns the piston member 35 to the position shown, this being arranged to occur after the deduction chamber 43 is disconnected from the pumping chamber 9. When the chambers 9, 43 are again connected, the deducted fuel can flow through the return passage 38 into the pumping chamber 9. As the speed increases the piston member 35 has a shorter time in which to complete its return stroke and thus the amount of fuel returned progressively decreases and thus also the amount deducted during the next stroke. Eventually the piston 35 has insufficient time to return before the next injection stroke. Below a certain speed the deduction chamber may be disconnected from the pumping chamber by a valve, Figs. 10 and 11 (not shown) responsive to accelerator lever position or feed pump pressure.
